SNI1 governs how temperature reshapes crossovers and genetic diversity - Nature Plants
2+ hour, 22+ min ago (223+ words) Nature Plants (2026) Cite this article Cooler temperature alters the frequency and genomic sites of chromosomal DNA exchange during reproduction in Arabidopsis thaliana. This response depends on SNI1, a chromosome-architecture factor that acts as a temperature-sensitive brake on crossover formation and helps…...
NASA Sends 12.5 Million Tomato Seeds to Space for a Year, but Challenger Tragedy Delays Recovery, Leaving Them in Orbit for Nearly Six Years
5+ hour, 59+ min ago (936+ words) In 1984, NASA launched 12.5 million tomato seeds on an orbital platform, intending to retrieve them less than a year later. The goal was to determine whether exposure to the space environment would affect germination and plant growth, according to Compre Rural....

Melatonin-Soaked Seeds Help Tomato Seedlings Fight Cadmium and Drought
4+ hour, 20+ min ago (94+ words) A simple soak in melatonin, the same hormone that governs sleep in humans, may hold the key to protecting one of the world’s most valuable vegetable crops from two of its most punishing environmental threats. New research published in Plant…...
Rotten-Egg Gas Helps Okra Beat Salt Stress Through a Hidden Hormonal
5+ hour, 8+ min ago (533+ words) Hydrogen sulfide, the gas best known for its smell of rotten eggs, is emerging as one of the most surprising heroes of plant stress biology....
A bright future for drought-resistant sunflowers
18+ hour, 3+ min ago (589+ words) | HelEx Project | Results in Brief | HORIZON CORDIS | European Commission The EU-funded HelEx project has developed new sunflower varieties with increased drought- and heat-tolerance, as well as pollinator-friendly and high-protein cultivars. These could help boost crop productivity and create new revenue…...
Groundnut Stem Rot Resistance Is Inherited Through Incomplete Dominance,
9+ hour, 10+ min ago (570+ words) A new genetic study from India has revealed how resistance to one of groundnut’s most destructive diseases is passed from one generation to the next, and the answer carries immediate consequences for breeders racing to develop tougher varieties. Researchers at…...
Green-Synthesized Silver Nanoparticles Boost Tomato Defenses at the Right
10+ hour, 44+ min ago (548+ words) Tomato growers battling bacterial wilt and speck may soon have a new tool that works in two directions at once....
Twisted Peptide Shape Reveals How Plants Reopen Stomata After Immune Alarm
14+ hour, 53+ min ago (77+ words) Every leaf faces a dilemma. The microscopic pores called stomata that dot the plant epidermis are simultaneously the gateways for carbon dioxide intake and the entry points for bacterial and fungal invaders. When pathogens attack, plants slam these pores shut…...
Could You Combine Two Seeds — or Two Fathers — to Create Something New?
16+ hour, 14+ min ago (1214+ words) Imagine cutting a pine tree seed in half. Then imagine taking half of a seed from a completely different tree—perhaps one that produces brilliant pink flowers—and somehow joining the two pieces together. Could you plant it and grow…...
